Unroll crescent rolls, but do not separate into triangles. On a lightly floured surface, press dough edges together and roll out slightly to fit dish. Place dough over the cheese layer. Brush with melted butter and sprinkle with Parmesan cheese. Bake, uncovered, in a 375 degrees oven for 20 to 25 minutes or until top is deep golden brown.
